To aZZ 'whom ibm/.cry concern.-

Beit known that I, JOHN S. ROAKE, a citizen of the United'States,'residing in the city of` New York, borough of Brooklyn, in the county 5 of Kings and State of New York, have invent# ed a certain new and useful Improvement in `Distilling Apparatus, of which the following is a specification. I l

The invention relates to means for sepa-f to rating certain heavyvportions and impurities carried over in the vapor from the retort and removing them before liquefaction in the con-- denser. l The invention is intended more particularly t5 for service in-'the distillation of Wood in ob-..

taining turpentine,pyroligneous acid, and other products.

iined by the appended claims;

'V c' The accompanying drawings form a part of this specification and show the invention as I have carried it out.'

Figure 1 isa side elevation, partly in vertical section, showing the separating-chamz 5 ber and so much of the other-portions ofthe Similar letters of referencel indicate the Y same parts in all the figures. l 3 5 A is a retort, which may be of any ordinary or approved construction, provided with, means for supplying heat to its contents and` with other usual equipments, and A' is the vapor-pipe leading therefrom to the separat' ing-chamber B, to be described. 4

A2 is practically ya continuation of the vapor-pipe from the chamberB to the worm G, inclosed in atank C' and provided with means (not shown),for cooling the vapor and induc- 45 ing condensation,- as usual.

The chamber B is preferably cylindrical, With its axis vertical, having the top domed, as shown, and provided With'the ianged central boss B', to which is secured the vapor- 5o pipe A, and the angularly-faced boss B2, re-

The novel features will be speciically de corresponding to Fig. l, and Fig. 'Sis a trans- :the desired position. I Vapor produced in the retort A flows through the pipeA' and is projected downwardly in `.thechamber through the pipe M :Any heavy l ceiving the exit vapor-pipe A2. The bottom Bs of the chamber is concave and is hinged at b, so that it may be swung downward to expose the whole open area of the chamber,

and B4 is a fastening means-by which the bot- `5 5 i tom may be secured in the closed position. A boss B5 at the center of the bottom receives 'a pipe D at the'lowest point, provided With a valve D' and trap D2, leading to a recepta-A cle D3. M is a pipe secured on the inner face of the top of the chamber and extendingV axially u downward nearly tothev bottom B2 and is in effect an extension Aof the pipe A',- serving'to deliver the vapor received through the latter 6 5 ata low level in the chamber. l

N N' are two 4gratings or trays, each comprising a series of annular troughs N2, of semi` circular section, joined at intervals by the connecting-ribs N2 and having a downwardly- 7o i projecting annular fin N4, forming the termination of the under face of each trough. The open-work trays are supportedon lugs b' b on the interior of the chamber matching to'cor'responding notches 'n n in the periph- 75 eries of the trays, allowing them to be easily introducedfrom below when the bottom B2 is swung Open. The troughs are so arranged that Wheninplace in the chamber 'the fins N4 on the uppermost tray N will lie immediately 8o 'above the annular. openings between the` 'troughs on the lowermost N', so that liquid dripping from the iins may fall unobstructedly to the bottom of thechamber. Each tray has a central guide-ringrN5 encircling the 85 l pipe M and vserving to maintain the trays in matter'entrainedor held in suspension mechanically in the vapor Will'be thrown by its momentum upon the bottom B2, to Which it will adhere and if sufficiently fluid will gather -Y and flow downward through the pipe D to the 95 receptacle D2. The vapor rises in the chamber, as indicated by the arrows; but as the diameter of the chamber is considerably greater than that of the pipes A', A2, and M the ascent is proportionately slower, andoprco portunity is thus afforded for any remaining heavy matter in the vapor to separate by gravity and accumulate in the lower portion of the chamber, whence it flows to the receptacle D3, or the heavy particles may adhere in the forni of liquid upon the surfaces of the trays N N and drop from the annular ns N4 to the bottom and iiow away. The lighter portions of the vapor pass out of the chamber through the pipe A2 and iiow to the Worm C and are condensed, as usual.

The delivery of vapor from the retort to the worm is not retarded nor interrupted; but by reason of the great difference in crosssectional area between the vapor-pipe and chamber the flowvthrough the latter is much slower and the entrained heavy matter is given time to separate and descend.

The material supplied to the trays N N' maybe varied to suit requirements. Lime supplied in certain portions ofthe process of wood distillation will serve usefully in combining with pyroligueous acid and aiding in its removal. The lime thus combined may on its removal from the trays be treated to produce acetate of lime.

Modifications may be made in the forms and proportions without departing from the invention and parts may be used without the whole. The trays N N may be differently formed and a greater or less number than here shown may be employed.

The relative sizes of the vapor-pipe and chamber should be such as to produce the required slow movement of the vapor through the chamber and vallow the heavy matter to separate and will be determined by the materials treated and the conditions of the distlling process.

Although I have described the invention as applied to the distillation of wood, it will be understood that it will serve successfully in other distilling operations.

l, In a distilling apparatus,a vapor-pipe leading from the retort to the worm, combined with a chamber of greater cross-section al area than said pipe interposed in the same between the retort and worm, and a series of open-work trays in said chamber said trays having alternately-arranged fins, as and for the purpose specified.

2. In a distilling apparatus, a retort, a vapor-pipe therefrom ,a chamber of greater crosssectional area than said pipe and to which said pipe leads, a downward extension of said pipe within said chamber,a vapor-pipe of less crosssectional area than said chamber leading from the upper portion of the latter to the Worm, and a plurality of receptacles within the chamber above the lower end of the extension and havin g alternately-arran ged fi ns, all combined and arranged to serve substantially as described` 3. In a distilling apparatus, a retort, a vapor-pipe therefrom,a chamber of greater crosssectional area than said pipe and to which said pipe leads, adownward extension of said pipe within said chamber, one or more open-work trays inclosed in said chamber with their annular troughs alternatelyarranged and adapted to support and present a combining agent to the vapor in said chamber, and a vapor-pipe of less cross-sectional area than said chamber leading from the upper portion of the latter to the worm, all combined and arranged to serve substantially as herein specified.

4. The retort A, vapor-pipe A and chamber B, the extension M Within said chamber, the open-work trays N N inclosed in the latter one above the other, each comprising a series of annular troughs N'Ehaviug the annular fins N4, the iins on the uppermost tray coinciding with the annular spaces between adjacent troughs on the lowermost, the vapor-pipe A2 leading from the upper portion of said cl1amber to a worm, the hinged bottom B3 for said chamber, and a pipe D leading therefrom, all combined substantially as and for the pur poses herein specified.

5. A retort, a chamber, a vapor-pipe connecting the two and having an extension within said chamber, open-work trays inclosed in said chamber one above the other, each comprising a series of annular troughs having annular iins, the fins on the one corresponding with the 'annular spaces between,` adjacent trays on the next adjacent, a vapor-pipe leading from the upper portion of the chamber to a worm, and an outlet from the bottom of said chamber, all substantially as described.

In testimony that I claim the invention above set forth I ailix my signature in presence of two witnesses.
